Utilizing two 6V6 power tubes, one 12AY7 preamp tube, and one 12AX7 preamp tube, the circuit is simple enough to maintain a rich harmonic composition but powerful enough for guitarists to use in recording studios, rehearsals and smaller venues - and the amp is just a microphone away from being ready for bigger stages. At higher volumes, this amp produces saturated tones that were adopted as signature tones for the likes of Billy Gibbons, Neil Young, Don Felder, and Larry Carlton. These amps were originally designed as medium power amps that would allow a musician to plug in more than one amplified instrument at a time. Mojotone’s Tweed Deluxe Style Amp is based on the popular 5E3 circuit from the 1950s and is by far our most popular amplifier. Please read our article 'Mojotone Amp Kit Building Primer' along with our amp kit disclaimer located in the Specs tab before buying this kit. He was very emphatic about safety and his writing was extensive.If this kit shows as out of stock please check here for more information. I think there is still a guide published by Nuuk around somewhere. Make sure you read lots before you start especially about safety. The only real drawback is that you have to work with line voltage so a mistake could be fatal. Personally, I like the pcb because grounding is a PITA (I'm a hack hobbiest) and if youre hacking together a circuit on perf board it will give you one more thing that could be a problem. You can easily buy the parts from digikey and assemble on perf board, or find a pcb. You will have to hunt around if you want a kit and you should probably steer clear of the eBay kits which have been rumoured to often contain counterfeit parts. Nelson Pass has an article about these, and Sigfried Linkwitz used 6 of them to power an earlier version of his open baffle speaker. What's more, the circuit is one of many "utility circuits" often listed as circuits you should know as a tech or engineer. It has around 8 components, but sound truly great, and is inexpensive. Lm3886! Also called gainclone after a ludicrous commercial amp called gaincard that used the recommended application notes off product sheet (so I've read) and then sold the amp for around $3000 in year 2000 dollars. But barring that a kit amp would at least be like the workbook problems and force me to think it through a bit and also validate it to some degree. If there is a build a virtual amplifier kit out there, that explains what each part does and lets you play with parameters, I would give that a shot first, since my current amps are certainly good enough. Everything seems to be for experts (here’s the diagram have fun! or here’s a circuit simulator. I tried playing with some online circuit building software, but I need more hand holding than that. I have this feeling like I’m just not getting it, which bugs the crap out of me. Or looking at circuit diagrams and they mostly make sense, but then certain parts don’t. I get in to discussions here or read them, about Zout and its impact on speakers and I get lost. Back in high school calculus, I remember never feeling like I understood until I successfully solved enough problems. I can read about programming language, but if I don’t actually code in it, it feels very fragile. While most have been fine, have had a couple of unsuccessful projects and that is not fun. Should mention that in all cases my DIY goal has always been to have a useful product in the end. In the end, a simple lower power amp like the Akitika might be educational, but is no substitute for years of experience IMO. This was before op-amps and is somewhat better now, but have read up more on amp design and understand why my EE buddies got cold feet. It never got built unfortunately as I wanted the experience as I think you do. I bought the parts to build and they backpeddled and said they would have to build it to ensure stability. When I was first hired (mid 1980s) some EEs had knocked off a Threshold amp. After some serious studying decades later, am still barely functioning when it comes to analog. That is when I switched to computer science as a major. After my first digital design class, was somewhat dismayed that it was not as clearcut as I expected. Being good at analog circuit design requires real experience.
